Leap Days Clipper Parade: February 26th-29th 2020
John1122 replied to John1122's topic in Tennessee Valley
MRX actually added my area to the WWA but for elevations higher than me. Holding at 31 degrees up from 25 as the atmosphere tries to saturate. The ground is nicely frozen after being sub freezing for the last 12 hours. Just need to see the moisture actually reach the surface. -

Looks like the best shot of anything sticking lower that 1500ft will be tonight after dark with the second wave. -

One difference from tonight into tomorrow vs yesterday, we had been above freezing and had to work our way below freezing on a warmer ground. No worries about that tonight. -

Speaking earlier about location during upslope, LeConte is a few miles from Newfound Gap but picked up 7 inches of snow into this morning. Newfound Gap only got an inch. -

On the 00z HRRR 700-500mb Lapse rates look to be -7 to -8 in the area into tomorrow. Not absolutely unstable like -10 or more but enough to be considered conditionally unstable. HRRR is .5 to 2 inches over a good part of the Eastern Rim and other areas eastward. The 3+ lollipop shows up in western Cumberland County. The mountains go for 4-8 inches. -

OHX seems to be all in for their Eastern counties. WWA for 1-2 inches plus some more Friday night with a 3rd clipper. MRX less enthusiastic. -

Had an 8 foot deep mega pothole/sinkhole open in an area roadway this week. There was a huge one in a backyard a couple weeks ago. -

Flow snow is fickle. Elevation helped a lot last night too. -

Models look like they are keying on the Southern Plateau for a bullseye spot with the next clipper. Outside the Eastern mountains that area shows up as the winner across 6z/0z model runs. -

Pretty good NW flow snow going right now. Temp is 28, hopefully I can keep this going until morning. May squeeze out an inch. -

It's the GFS, so probably wrong, but it's pretty aggressive with Clipper 2. -

Dusting here with steady snow falling. Not even showing on radar here. With dealing with flow snow in my area only pretty heavy stuff shows up on radar. -

Heavier bands have covered some roads in my area too, even in southern Campbell at lower elevations. Multiple trees down across the county too. Was a potent cold front. -

Steady snow falling now. Looks like even far western areas are seeing streamers. -

I'd guess it reaches the valley areas. Probably earlier than forecast too. My point forecast said 10pm. It switched before 5pm here. Wind has now knocked out the power here. -

Second the wind Holston referred to. Its gusting over 30 here, especially during snow showers. Just drove across town in a sideways shower. -

The RGEM has in the past been decently skilled with the Northern stream activity. It has the 1st event Wednesday into Thursday. The next isn't in range for it yet. -

There's a possibility of convective snow showers with these disturbances. If you get under one you can see very heavy snow and strong wind for brief periods of time. The GFS advertises some flakes basically statewide. -
A series of clippers looks likely, they are notoriously fickle in the area. Earlier the Saturday clipper was showing up for West Tennessee but now looks like it's shifted east. As always the higher up the better. I wouldn't be shocked to see the Smokies end up with over a foot when it's all said and done. The Plateau could get a few inches as well. Crossville to my area seems to be in the 1-3 inch range through Saturday. As always it will depend on timing and surface temps. Night would be much better.

.76 rain today. Also had sleet off and on at times. It was sleeting as late as 2:30 this afternoon. Very cold layer aloft today, noticed that it was 25 at Clingmans Dome with freezing rain a little while ago.

Wild Speculation for Winter 20 -21
John1122 replied to Holston_River_Rambler's topic in Tennessee Valley
2012 ended up being the lowest summer ice extent on record due to a very unfavorable pattern that developed in spring and summer over the Arctic. 2012 at this time of year wasn't remotely the lowest ice extent on record. We are slightly ahead of 2012 right now and overall this winter has seen gains in Arctic ice that easily outpaced average. Currently sea is is ahead of 2019 on this date, well ahead of 2018 on this date, well ahead of 2017 on this date, well ahead of 2016 on this date, ahead of 2015 on this date, ahead of 2014 on this date, roughly tied with 2013 on this date, ahead of 2011 on this date, roughly tied with 2010, behind 2009 and 2008, ahead of 2007, ahead of 2006, ahead of 2005, behind 2004-2001. So in the last 20 years we are currently ahead on Arctic sea ice vs 14 of the 20 years. So the +AO has done pretty good work in the Arctic this year.
